Just because it’s not sold doesn’t mean they’re “critically endangered”. You can get most if not all ROMs on the internet.

this is referring to them being officially available for purchase

Yeah but what can you do if a lot of the companies who made the original games aren’t around anymore and didn’t sell the rights to anyone else? Even some of the people who claim piracy is immoral understand that “pirating” abandonware is perfectly fine.

I would rather not call that piracy but latent preservation.

I do love latent preservating games I never owned
